How does Line CLI store my sign-in on my computer?

Line saves its sign-in in ~/.config/line/auth.json.

How it's protected#

• On macOS and Linux, Line makes the config folder and its files private to your user (other users on the machine can't read them).
• Commands Line runs, plugins and hooks don't get Line's own sign-in token in their environment.
• line logout revokes the token and deletes the file.

Keep it safe#

• Don't share or commit ~/.config/line (it holds your sign-in and sessions).
• If you think someone copied it, run line logout (or sign out of all sessions from your account's security settings), then sign in again.
